Error: Connection activation failed: Can not find a master for bridge0: Master connection not found or invalid

.

Questions:

Has anyone experience this particular issue?

If yes to question one, is there a workaround? Besides using an alternative method, I particularly would like to get this to work with NM

EDIT: Problem fixed, I was missing the "bridge" kernel module, while tackling another approach for the time being. I updated the Kernel, with NetworkManager vague error wording, and no useful error messages in "dmesg", that it didn't occur to me I needed to reboot into the newer kernel.
